How it works

From an idea to a factory file in three steps

No packaging engineering, no Illustrator templates to redraw. If you can measure your figure, you can make the box.

  1. 01

    Pick a box, type the size

    Choose a structure and enter the inside length, depth and height in millimetres plus your board thickness. Lids, tuck flaps, dust flaps and glue tab redraw instantly around your figure.

  2. 02

    Add your characters

    Name each figure, pick its colour, upload its art, and mark one as the hidden chase. Fronts change per character; the back roster stays shared.

  3. 03

    Check in 3D, then export

    Fold it on screen to catch mistakes early. Export vector PDF + SVG your printer can cut from — one SKU with Pro, or the whole series as a ZIP with Series.

Box types

The structures toy brands actually ship in

Every one is parametric: change a number and the whole dieline, including the 3D model, rebuilds.

Straight tuck-end box rendered in 3D

Straight tuck-end

The blind-box classic. Both lids hinge from the back, tucks close at the front.

Reverse tuck-end box rendered in 3D

Reverse tuck-end

Retail carton with lids on opposite panels — cheaper on the press sheet.

Lock-bottom carton rendered in 3D

Lock bottom (1-2-3)

Snap-lock base that folds shut without glue. Sturdier than a tuck for heavier vinyl.

Window box with hang tab rendered in 3D

Window + hang tab

Show the figure through a die-cut window; optional euro slot for pegs.

Roll-end tuck-front mailer box rendered in 3D

Mailer (tuck front)

Roll-end mailer with double side walls and a front tuck — for PR kits and collector sets.

Counter display tray holding six boxes rendered in 3D

Counter display tray

Sized automatically to hold 6–12 of your unit boxes.

Series export

Built for lines, not one-offs

Generic dieline tools give you one box at a time. A blind box drop is six, nine, twelve boxes that must match to the millimetre. Seriesfold treats the series as the unit of work.

  • Unique fronts, shared back. Each character gets its own front panel; the back shows the full roster.
  • Hidden figure, handled. The chase shows only a silhouette on its front, and stays a silhouette on the back roster unless you choose to reveal it.
  • Matching tray included. The counter display is sized from your unit box and count.
  • One ZIP for the factory. Every SKU as PDF + SVG, plus DXF cut/crease files for the die-maker, named and ready to send.

Why Seriesfold

Made for small brands with big shelves to fill

Files printers accept

Vector PDF at 1:1 with Artwork, Bleed, Crease and Cut on separate layers and fonts embedded, plus a layered SVG for Illustrator, Affinity or Inkscape.

See it before you pay for samples

The 3D preview folds along the same crease lines as the file, so a flap that collides on screen would collide in your hands.

Your art stays on your computer

Everything is drawn in your browser. Uploaded character art is never sent to our servers.

Exact millimetres, board included

You type inside dimensions; panels grow by the board thickness and tucks narrow to slide in, so the box fits the figure, not just the drawing.

Back-panel blocks in place

Barcode, origin and age-grade areas are laid out for you as placeholders, ready for your real data.

Fair, simple pricing

Free to design. Pay once for single-box files or once for a whole series. No subscription, and commercial use is included on every paid plan.

FAQ

Questions makers ask

Something else? Open Help & feedback or email support@seriesfold.com.

I'm not a packaging designer. Can I still use this?

Yes — that's who it's for. You only need your figure's size and your artwork. Seriesfold draws the flaps, tucks, glue tab and bleed, and the 3D preview folds along the same crease lines as the file.

Which file formats do I get, and will my printer accept them?

Pro exports a vector PDF and an SVG at 1:1 scale in millimetres; Series adds a DXF of the cut and crease lines for the die-maker. In the PDF, Artwork, Bleed, Crease, Cut and Guides are separate layers, cut / crease lines use named spot colours (CutContour, Crease), and the page has TrimBox / BleedBox set. Text in the SVG is converted to outlines, so the printer needs no fonts. Always ask your printer for a physical white sample before a full run.

Are the colours CMYK?

No — artwork colours in the files are RGB. Your printer converts them to CMYK, so a bright brand red can print slightly darker. For colour-critical jobs, ask for a colour proof, or place your own CMYK artwork on the Artwork layer of the PDF in Illustrator.

Why are the crease lines solid?

Many die-makers read a dashed line as a perforation (cut-and-tie) rule, so creases are solid by default and told apart from cuts by colour and by the spot-colour name "Crease". If your printer prefers dashed creases, tick "Dashed crease lines" before exporting.

Which board thickness is supported?

Enter the board (paper) thickness from 0.2 to 3 mm. Inside dimensions stay exactly what you typed: each wall panel grows by one board thickness, the body height by two, lids match the depth panel, and tuck flaps are narrowed so they slide inside. Typical values: 0.35–0.45 mm for folding carton (300–400 gsm), 1.5 mm for E-flute mailers. Proof on your real stock.

Which box types are there?

Straight tuck-end, reverse tuck-end, a 1-2-3 lock bottom (snap-lock, no glue), a window box with hang tab, a roll-end tuck-front mailer with double side walls and lid dust flaps, and a counter display tray sized from your unit box. A pre-glued crash-lock (auto-bottom) is on the roadmap.

Which side of the display tray is printed?

The tray is printed on the inside: the header card and the inside of the back and side walls carry the artwork, because that is what shoppers see when the boxes stand in it. The outside of the low front lip stays plain board. Fold a white sample first; if you need a printed front, ask your printer for a double (folded-back) front lip.

What's the difference between Pro and Series?

Pro ($19 one-time) exports print-ready PDF + SVG for one character box at a time, with a single-SKU back panel. Series ($49 one-time) adds everything a factory run of a whole line needs: the one-click series ZIP (every character's PDF + SVG), the shared back roster with the hidden figure, the matching counter display tray, and DXF files for the die-maker. You can upgrade from Pro to Series later by paying the difference — just email us.

What does the free plan include?

All box types, exact sizing, the series setup and the full 3D preview, with no time limit. You can download a watermarked PNG preview to share with your team or client. Print-ready files need Pro or Series.

Is it a subscription?

No. Pro and Series are one-time payments with no auto-renewal. Your purchase includes updates to the features of your plan.

Can I sell products that use boxes made with Seriesfold?

Yes. Commercial use is included on every paid plan, and the artwork and files you export are yours. You may send the files to any printer or client.

How do I pay, and do I get an invoice?

Checkout is handled by Creem, our merchant of record. Creem charges your card, handles sales tax / VAT and emails you a receipt (invoice) automatically. If you need a company name or tax ID on it, reply to that receipt email or write to us.

How do I receive my license?

After checkout you get a license key by email. Paste it into the app under "Have a license key?" and paid exports unlock in that browser. Each key can be activated in several browsers (for example your office and home computers); to move it, see “Changed computer or browser?” below.

Changed computer or browser?

Each browser you unlock (a new laptop, another browser, a private window, or the same browser after clearing its data) uses one activation of your key. Before you switch, open the app in the old browser, open “Have a license key?” and click Remove this browser: that frees the activation, and you can paste the key in the new browser. If the old computer is gone or you have run out of activations, email support@seriesfold.com with your key (or order email) and we will free the old activations for you.

Do you offer refunds?

Yes. If the files don't work for you, you get a full refund within 14 days. Just email us with your Creem order number. See our refund policy.

Is my artwork uploaded anywhere?

No. The app runs in your browser and your images stay on your device. Only messages you send through the Help & feedback form reach us. See our privacy policy.

Which images can I upload for my characters?

PNG with a transparent background works best (the hidden figure’s silhouette is cut from its transparency). SVG, JPEG and WebP work too; SVG and WebP are converted to a high-resolution PNG for print. For sharp printing use at least 300 dpi at the printed size — the app warns you if an image is too small.

How should I test a box before printing thousands?

Print the PDF on plain A4 or Letter at 100% scale ("Actual size", not "Fit to page"), check that the 50 mm scale bar measures 50 mm, cut on the red lines, score the blue lines, and fold it around your figure. Then order a white sample from your printer on the real board. Our own geometry is checked by automated tests on every box type; physical white samples are in progress.

How do I contact you?

Use the Help & feedback button on any page, or email support@seriesfold.com. We usually reply within two working days.

Your next series deserves a proper box.
